Description

Open soon large flow sterile valve

Technical field

The utility model relates to a kind of valve, relate in particular to a kind of can left and right open open soon large flow sterile valve, belong to valve technology field.

Background technique

Stop valve can be divided into straight-through stop valve, Oblique Stop Valve, Angle Stop valves and plunger stop valve by channel direction.

The open-shut device of stop valve is the flap of stopper, and sealing surface is plane or the conical surface, and flap is along the center line moving linearly of valve seat, and the forms of motion of valve rod refers to the valve that flap moves along valve seat center line, and flap blocks up on the opening of two partitions formation on valve pocket.

The break-make of stop valve realizes by the mobile of flap, and in actual use, flap may with valve pocket in partition block or block-up position has deviation, thereby make flap and valve pocket is poorly sealed causes leakage.Existing stop valve is long-term mobile in addition easily causes plunger partly to wear and tear, and causes the damage of equipment, while operating simultaneously, need several circles of rotary handle even more multi-turn just understand Open valve, switch valve comparatively bothers.

Existing valve seal is poor in addition, can not meet gnotobasis demand, and easy cleaning, not easy to assemble not, uses inconvenience, and permanent rotation has reduced its working life.

Summary of the invention

In order to solve problems of the prior art and deficiency, the utility model provides a kind of large flow sterile valve of opening soon, by the redesign to flap, no longer moving along valve seat center line of flap, realize the left and right of valve and open the unlatching that 90 degree can be realized valve, switch is more flexible, and wear resistance is better, better tightness, easy to assemble, easy cleaning, can not reveal, extend the working life of valve, can meet gnotobasis requirement.

The purpose of this utility model is to realize by following technological scheme

Open soon large flow sterile valve, in structure, comprise handwheel, valve rod, valve gap, valve body, flap and sealing circle body, handwheel connects valve rod, in valve body, be formed with valve pocket, valve rod is connected with flap in valve pocket through valve gap, flap below is provided with sealing circle body, and sealing circle body is fixed in the opening of two partition formation in valve pocket.

Described sealing circle body, its integral body is wave-like type, its middle part has a waveform seal ring at least.

Described valve gap, is connected with pressure cap on it, be provided with trim ring and seal ring in pressure cap, under valve gap, connects valve body.

Described valve body, has two partitions in it, valve pocket internal channel direction has straight-through type, direct current type or right-angle type.

Described flap, comprise valve petal body, spool, airtight circle, spool lower device is in valve petal body, airtight coil apparatus is in valve petal body lower end, on valve petal body, have water outlet, valve petal body upper cap nut place is provided with seal ring, there is a fixing column spool top, fixing column outer surface has seamed edge, and in the seal groove of spool near middle, correspondence is provided with three seals circle, and spool bottom is swing leg, swing leg connects arc lobe, arc lobe below is the lobe of intaking, and there is fin at water inlet lobe two ends, and fin correspondence is arranged in the groove in valve petal body lower inner wall.

Described arc lobe, it is whole like Bow, and on it, one side has symmetrical fixed groove, and another side is plane, and the limit of fixed groove both sides on arc lobe is arc-shaped side, forms arc opening.

Described water inlet lobe, correspondingly with arc opening on it is provided with two water intakes.

Described arc lobe and water inlet lobe, adopt the high-abrasive materials such as silicon carbide to make, and wear resistance is better.

During use, flap is connected with valve rod, and flap is pressed and fixed in the opening in valve pocket, by anticlockwise or right rotation handwheel, realize 90 degree rotations of arc lobe, get final product the break-make of control valve.

The utility model has changed motion mode and the structure of traditional stop valve, flap no longer moves along valve gap center line, by handwheel, control the rotation of arc lobe, realize the quick break-make of valve, switch is more flexible, wear resistance is better, there will not be and reveals the problem losing efficacy, and has greatly extended the working life of valve.

Owing to having adopted above technological scheme, the utility model also has following beneficial effect: 1) whole and isolated from atmosphere is guaranteed aseptic; 2) valve pocket is smooth without dead angle; 3) easily clean; 4) good seal performance; 5) high temperature resistant; 6) long service life; 7) safeguard that dismounting is simple; 8) at the bottom of maintenance cost; 9) the large non-resistance of flow.
